Product Description:

The CSB02.1B-ET-EC-EC-S5-NN-NN-FW is a modular drive controller produced by Bosch Rexroth Indramat within the CSB Drive Controllers series. It serves as the central axis node for servo and induction motor installations, issuing position, velocity, and safety commands to actuators in automated equipment. By combining network interfaces, encoder supply, and signal conditioning in one housing, the unit reduces cabinet wiring and simplifies integration on production lines. This arrangement also allows control signals and feedback paths to be managed from a compact central module.

The controller supplies feedback devices with a regulated encoder current of 500 mA. Three analog input channels monitor process signals, while two analog outputs provide a controllable span of ±10 V. Each output step has a resolution of 24 mV/incr, allowing fine reference adjustments to external amplifiers. For discrete control, the front panel provides 11 digital inputs that accept 24 V logic. Motion data arriving on the EC interface is digitized by a 12-bit A/D converter, and probe inputs allow event-based signals to be handled alongside continuous analog data. This combination lets the controller process sensor values, reference signals, and switching states within the same control path.

Field communication is handled through the Multi-Ethernet backplane, and the ET port carries deterministic traffic over 100Base-TX. The connection uses an RJ-45, 8-pin connector for standard cabling. Encoder feedback passes through an EC sine front end with a cutoff frequency of 400 kHz, which supports high-resolution transducers without aliasing. Filtering at the input stage helps preserve signal quality before the control electronics evaluate position data. The same terminal assembly includes safe input and safe output channels for connection to external emergency circuits. Safe Motion functions conforming to Safe Motion (S5) supervise speed, direction, and standstill without removing main power.
